SPT WA-1420E Air Filter
It is highly recommended that the filter that filters out particles from your home is exchanged for a new one four times a year due to the filter clogging up and restricting the flow of air throughout the home. Air Filters are made in lots of types and sizes, depending on your desire for cleaner air and air handler size requirements. The height, length and width of the filter is not a optional choice because it is based on the declared size of your furnace or handler.
Key symptoms of a weakening dust filter
- It is greatly recommended to switch out the air filter in your unit every season of the year to help prevent mold and bacteria build-up
- It looks gray or brown and maybe should be replaced right now
- With a light behind the air filter, the light will not shine on the opposite side of the dirt filled filter
